which pass within apertures '20, flange 9 embracing a part of the end of the vertical strip and the .outerrface of the horizontal strip. The inner face of thehorizontal strip. may have the short, wing or flap '6 seated thereon, and a part of flange .5'ma'y be disposed upon saidwing 6,-the remaining part "of this flange being seated upon the inner face of said horizontal :strip and secured thereto by means of suitable keepers or nails 21, whichmay pass through apertures 22, provided for this purposelEn instances where it is desired to secure 7 the corners of frames of heavy structure, two

corner pieces may be employed if desired, and mounted opposite to each other and bearing upon the sides of the horizontal and vertical strips, as illustrated in Fig. 1, and

" they providea reliable holding means for connecting the adjacent ends of the strips.

The devlce may be conveniently used for repairing weakened frames to strengthen their corners, and is particularly useful in connection with the manufacture-of screen frames. As shown in Fig. 6, the wire gauze or screen cloth may be secured upon the frame by use of the conventional molding and 12, for use when commencing to nail the 1 wire cloth: upon the screen frame.
